Example 1
As shown in fig. 1 to 4, a first embodiment provides a pressure maintaining device including: the pressure maintaining device comprises a connecting seat 100, a pressure maintaining head assembly 200 connected to the connecting seat 100 and a power mechanism for driving the pressure maintaining head assembly 200 to move; the pressure maintaining head assembly 200 comprises a fixed block 210 fixedly arranged on the connecting seat 100, a middle block 220 connected to the fixed block 210, a pressure maintaining head seat 230 connected to the middle block 220 and a pressure maintaining head 240 connected to the pressure maintaining head seat 230; the middle block 220 is hinged with the fixed block 210 through a first pin shaft 250, the pressure maintaining headstock 230 is hinged with the middle block 220 through a second pin shaft 260, the first pin shaft 250 and the second pin shaft 260 are vertically arranged, and the fixed block 210, the middle block 220 and the pressure maintaining headstock 230 are detachably and fixedly connected.
In the packing apparatus, the packing head assembly 200 includes a fixing block 210, an intermediate block 220, a packing head seat 230 and a packing head 240, wherein the fixing block 210 is connected to the connection seat 100, and since the intermediate block 220 is hinged to the fixing block 210 through a first pin 250, the packing head seat 230 is hinged to the intermediate block 220 through a second pin 260, and thus, the intermediate block 220 can rotate around the fixing block 210, and the packing head seat 230 can rotate around the intermediate block 220, namely: the pressure maintaining head 240 can rotate around the fixed block 210 and the middle block 220 respectively, and in addition, because the first pin shaft 250 and the second pin shaft 260 are vertically arranged, the pressure maintaining head 240 can rotate in two directions, namely, the pressure maintaining head 240 can realize angle adjustment in two directions, so that the pressure maintaining surface of the pressure maintaining material can keep relative level with the plane of the pressure maintaining head 240. After the angle adjustment is completed, the fixing block 210, the middle block 220 and the pressure maintaining head seat 230 are connected together, and the connecting seat 100 and the pressure maintaining head assembly 200 are driven by the power mechanism to move, so that the pressure maintaining process is realized.
From the above, the pressure maintaining device can maintain the pressure maintaining surface of the material to be maintained at a relative level with the plane of the pressure maintaining head 240, so that the material to be maintained is ensured to be uniformly maintained in the pressure maintaining process, and the pressure maintaining effect on the material is improved.
It should be noted that: when the pressure maintaining device is used as shown in fig. 1, the pressure maintaining head 240 can realize angular adjustment in both directions of the Y axis and the Z axis.
Specifically, the middle block 220 is hinged with the fixed block 210 through a first pin 250 and is locked by a screw; the pressure maintaining headstock 230 is hinged with the middle block 220 through a second pin shaft 260 and is locked through screws. When the angle of the pressure maintaining head 240 is adjusted, the screw is loosened first, so that the pressure maintaining head 240 can slightly rotate around the Y axis and the Z axis, fine adjustment of the pressure maintaining head 240 is realized, and after the angle of the pressure maintaining head 240 is adjusted, the pressure maintaining head 240 is locked by the screw.
It should be noted that, the aperture of the through hole formed on the middle block 220 and the pressure maintaining head seat 230 is larger than the outer diameter of the screw, so as to ensure that the screw can realize locking action.
In this embodiment, as shown in fig. 1, the power mechanism includes a base 300 slidably engaged with the connection base 100 and a power element (not shown in the drawings) for driving the base 300 to move; an elastic assembly 400 is arranged between the base 300 and the fixed block 210, one end of the elastic assembly 400 is connected with the base 300, and the other end is connected with the fixed block 210.
Wherein, the power element can be a motor or a cylinder; a sliding rail assembly is disposed between the connection base 100 and the base 300, so that the base 300 can move horizontally along the connection base 100, namely: the base 300 can move along the connection base 100 in a direction toward or away from the holding head 240.
With continued reference to fig. 1, the pressure maintaining head assembly 200 and the elastic assembly 400 form a pressure maintaining mechanism with a plurality of pressure maintaining mechanisms.
Because the pressure maintaining mechanisms are arranged in a plurality, the pressure maintaining mechanism can maintain the pressure of different materials at the same time or maintain the pressure of different parts of the same material at one time, thereby saving the time for pressure maintaining, reducing the total production time of equipment and greatly improving the production efficiency. In addition, the three pressure maintaining mechanisms are integrated together, so that space is saved, and the installation is convenient.
Based on the above embodiment, as shown in fig. 3, the elastic assembly 400 includes a spring 410 and a pre-compression adjustment block 420; the pre-pressing adjusting block 420 is connected to the base 300, one end of the spring 410 is connected with the pre-pressing adjusting block 420, and the other end is connected with the fixed block 210; the pre-compression adjustment block 420 is provided with an adjustment structure for adjusting the pre-compression amount of the spring 410.
The extension and retraction direction of the spring 410 is perpendicular to the plane of the pressure maintaining surface of the pressure maintaining head 240. The power element can drive the movement of the base 300 along the connection block 100, thereby compressing the spring 410.
In the above structure, when the material having the inclined surface is pressurized, the pressurizing head 240 is vertically pressed against the material, the base 300 continues to horizontally move forward to compress the spring 410, the end of the spring 410 receives the horizontal force F, the spring 410 is mounted according to the vertical pressurizing surface, the force F can be decomposed into the component force F1 along the axial direction of the spring 410 and the force F2 along the vertical axial direction, wherein the force F1 can compress the spring 410 and simultaneously pressurize the material by the pressurizing head 240; f2 only affects spring 410 (because spring 410 is a flexible body) and does not affect pressure maintaining head 240, thereby protecting pressure maintaining head 240 to some extent.
With continued reference to fig. 3, the adjusting structure includes a connecting member for connecting the base 300 and the pre-pressing adjusting block 420, a long through hole provided on the pre-pressing adjusting block 420, and a round through hole provided on the base 300; alternatively, the adjustment structure includes a connector for connecting the base 300 and the pre-pressing adjustment block 420, a circular through hole provided on the pre-pressing adjustment block 420, and a long through hole provided on the base 300.
Since one end of the spring 410 is connected to the pre-compression adjustment block 420 and the other end is connected to the fixing block 210, the fixing block 210 is connected to the connection base 100 (the position of the fixing block 210 is maintained), the pre-compression adjustment block 420 can change its relative position with the base 300 by the adjustment structure (the position of the pre-compression adjustment block 420 can be changed), and thus, the pre-compression amount of the spring 410 can be adjusted by the adjustment structure.
As shown in fig. 3, when the pre-compression adjustment block 420 is adjusted to the left, the pre-compression amount of the spring 410 becomes smaller, and the generated compression force is smaller; when the pre-compression adjustment block 420 is adjusted to the right, the pre-compression amount of the spring 410 becomes large, and the generated compression force is large.
As shown in fig. 4, the pre-pressing adjusting block 420 is provided with a long through hole, and the base 300 is provided with a round through hole. Wherein, the connecting piece can be selected from the screw.
In this embodiment, the base 300 is provided with grooves for accommodating the pre-pressing adjustment blocks 420, and the number of the grooves is equal to the number of the pre-pressing adjustment blocks 420; the end of the pre-pressing adjusting block 420 away from the spring 410 is provided with a jackscrew which is in threaded connection with the base 300 and is abutted against the pre-pressing adjusting block 420.
On the basis of the above embodiment, as shown in fig. 1 or 3, a pressure sensor 500 for collecting the compression force generated by the spring 410 is provided on each of the fixing blocks 210.
As shown in fig. 1, the pressure maintaining surface of at least one pressure maintaining head 240 is disposed at an angle with the pressure maintaining surface of the remaining pressure maintaining heads 240. The advantage of this setting is that, a plurality of pressurize faces pressurize simultaneously, when one of them face exists the angle with another face, can eliminate the side direction component of pressure head 240 to the pressurized material when the pressurize to guarantee to be moved by the pressurized material can not side, the pressurize effect is better.
With continued reference to fig. 1, the number of the pressure maintaining mechanisms in this embodiment is three, wherein the pressure maintaining surface of one pressure maintaining head 240 is disposed at an angle with the pressure maintaining surfaces of the other two pressure maintaining heads 240. Three pressure maintaining surfaces are adopted for simultaneously maintaining pressure, and when one surface and the other two surfaces have angles, the lateral component force of the pressure maintaining head 240 on the pressure-maintained material can be eliminated during pressure maintaining, so that the pressure-maintained material can not laterally move; alternatively, the arrangement can be adapted to situations where pressure is required for three parts of the same material, and where there is an angle between one part and the other two parts, for example: when the sealant at three different holes of the mobile phone is pressurized, an angle exists between one hole and the other two holes.
It should be noted that, in this embodiment, no limitation is imposed on the angle between the three pressure maintaining surfaces, and the angle may be adjusted accordingly as needed or in actual situations.
Three holding mechanisms will be described below as examples.
The working principle of the pressure maintaining device is as follows: in the three pressure maintaining mechanisms, when the base 300 compresses the springs 410, the strokes of the base 300 are consistent, the springs 410 are compressed to generate compression forces, and differences exist between the compression forces generated by the three springs 410 (due to installation and other reasons, even if the strokes of the base 300 are consistent, the precompression forces generated by the three springs 410 may not be consistent), so that the three compression forces are kept consistent as much as possible, in order to prevent the compressed materials from being excessively large or excessively small due to the pressure of a certain pressure maintaining head 240.
The working process of the pressure maintaining device is as follows: adjusting the relative level of the pressure maintaining head 240 and the required pressure maintaining material; the power element works to drive the base 300 to move a certain distance along the connecting seat 100, the springs 410 are compressed, at this time, the pressure sensors 500 respectively collect the compression forces of the springs 410 corresponding to the compression forces, and if the three compression forces are within the error (+/-0.2 KG) requirement range, adjustment is not needed; if the three compression forces do not meet the error requirement, the spring 410 with the minimum compression force needs to be adjusted by adjusting the pre-compression adjusting block 420 to increase the pre-compression force, so that the compression force of the spring 410 and the compression force of the rest springs 410 in the subsequent compression are ensured to be within the error range, after the adjustment, the base 300 continues to move forwards and is kept for a period of time, and finally the pressure maintaining head 240 leaves the pressure maintaining material.
Assume that: the power element drives the base 300 to move along the connecting seat 100 by 4mm, the compression force of one spring 410 is 25N, and the compression force of the other spring 410 is 30N, so that the precompression amount of the spring 410 with the compression force of 25N needs to be adjusted to increase the precompression force by 5N, and the compression forces of the three can meet the requirement finally.
Based on the above embodiment, the pressure sensor 500 is electrically connected to the control unit, which is electrically connected to the display.
Before using the pressure maintaining device, a safe pressure maintaining distance (namely, the compression amount of the spring 410) is set, and when the distance is reached, whether the pressure detected by the pressure sensor 500 reaches the set value or not, the spring 410 is not compressed any more, and an alarm window is popped up on a display, so that the damage to products is avoided.
